CGI.pm: a Perl module written by Lincoln Stein, a bioinformatics researcher at Cold Spring Harbor Laboratory, NY.
CGI.pm uses objects to create HTML forms on the fly and to parse their contents. It provides a simple API for parsing and interpreting query strings passed to CGI scripts with a rich set of functions for creating forms. Instead of remembering the syntax for HTML, you just make a series of Perl function calls.
As a student familiar with HTML and new to Perl, the advantage of this last point may be somewhat lost. A Perl programmer with little knowlege of HTML would have a different perspective.
